If you search on-line you'll find that 15 to 20 public figures have been named as paedophiles. Most of them are household names. If the ones who are still alive were arrested and put on trial it would destroy what is left of the reputation of both main political parties. The establishment has protected these men just as the Catholic Church protected its abusing priests and the BBC protected Jimmy Savile.
In the past it was possible to stop scandals of this magnitude coming to light. Enquiries were rigged, evidence suppressed, particularly obdurate witnesses made to shut up. Decent people conspired at this- preferring the comfort of ignorance. But times are changing. The paedophile scandal in the Church prepared the way, the Savile affair has moved things on. We are now more willing than ever before to believe evil of the good and great.
